com GENERAL DESCRIPTION The DS26519 is a single-chip 16-port framer and line interface unit (LIU) combination for T1, E1, and J1 applications.
Each port is independently configurable, supporting both long-haul and short-haul lines.
The DS26519 is nearly software compatible with the DS26528 and its derivatives.
